Close View of the Lightning Attachment Process Unveils the Streamer Zone Fine Structure

Marcelo M. F. Saba et al.

Summary: A close observation of lightning attachment to a building revealed new details about the dynamics of leader streamer zone. Upward leaders propagate steadily and unbranched, while downward negative leaders have multiple streamers. A plasma formation known as space stem was also observed.

Fine Structure of the Breakthrough Phase of the Attachment Process in a Natural Lightning Flash

Rubin Jiang et al.

Summary: A high-speed camera captured a lightning strike hitting a 325m tower, revealing that a common streamer zone forms when the bright tips of negative and positive leaders are >= 23m apart. During the breakthrough phase, both leaders extend their channels with enhanced luminosity and shorten the gap between them to 16m. The growth of a luminous segment within the leader connection path is interpreted as a new scenario for converting a high-impedance common streamer zone to a hot plasma channel.

Inferences on upward leader characteristics from measured currents

Amitabh Nag et al.

Summary: This study analyzed currents associated with upward unconnected leaders (UULs) initiated from the Kennedy Space Center Industrial Area Tower, providing important insights into the development and propagation of upward leaders. The UULs were found to exhibit a bipolar lightning phenomenon, transferring negative charge followed by positive charge to ground.

Insights on Space-Leader Characteristics and Evolution in Natural Negative Cloud-to-Ground Lightning

Hamza Khounate et al.

Summary: The study presents high-speed video camera observations of three negative stepped leaders in cloud-to-ground lightning flashes, showing that the characteristics of space leaders are likely influenced by stepped-leader line-charge-density, possibly evolving differently in flashes with higher return-stroke peak currents.
